LIFTER FOR MARKER-BARS OF PLANTERS.

Specification of Letters Patent.

Application filed January 3, 1914. Serial No. 810,232.

To all whom may concern Be it known that I, FRANK F. Non'rn, citi ,marker bar and guiding the bar during its upward and downward movement- Another object of the invention is to so construct the mechanism that the marker bar may be positioned to extend upon either side of the machine desired.

Another object of the invention is to so construct the operating mechanism that the inner end of the marker bar will be moved downwardly while the supporting arms for the bar are being swung to. a raised position. Another object of the invention is to so construct the operating mechanism that the rack bar which operates the supporting arms will also form means for pivotally mounting the marker bar. V

Another object of the invention is to so construct the operating mechanism that it may be readily connected with machines now on the market.

This invention is illustrated in the accompanying drawings wherein Figure 1 is a rear elevation of a planter with the improved marking device in place; Fig. 2 is a top plan view of therear end portion of the planter with the marker in place; Fig. 3 is an enlarged fragmentary view of the operating mechanism for the marker with the front wall of the housing removed;

Fig. 4: is a sectional view taken along thev line 1-4: of Fig. 1; Fig. 5 is a sectional view taken along the line 5-5 of Fig. 3; Fig. 6 is a sectional view taken along the line 6-6 of Fig. 1; and Fig. 7 is a perspective view of the outer end portion of one of the supporting arms.

The operating mechanism for the marking bar is carried by a supporting plate 10 which is connected with the frame 11 of a planter, such as a corn planter by means of the brackets 12 which also support the cross bar 13'. The frame of the planter is provided the legs 16 carried by the frame 11.

The. supporting arms 17 are provided with enlarged heads 18 which are pivotally mounted upon the pivot bolts 19' and are provided with teeth 20. A rack plate 21 is Patented Apr. 6, 1915. I

with the usual supporting wheels 14: and drlvers seat 15, which seat is mounted upon slidably mounted in a' housing 22, andis provided with teeth 28 which engage the teeth 20 of the head 18. This housing is provided with side openings through which theinner ends of the heads 18 project in order to engage the teeth 23, and is also provided with inner and outer slots arena 25 through which the pins 26 and 27 project. The marker bar 28 is' pivotally mounted upon the pin 27 and is engaged by the forked end 29 of one of the supportingarms 17. These supporting arms when in thevextended position shown in Fig. 1 have their outer end portions supported by hangers 30 which are carried by the cross bar 13. The outer-end portion of the marker has not been shown 7 since th1s marker bar is of the conventional type and may be provided at its outer end with any suitable means for marking the ground. A latch lever 31 which is of the bell-crank type is pivotally connected with v the base plate 10 as shown at 82 and has its latch engaging the rack 38. The arm 34 of the latch lever is provided with an enlarged head 35 in which there is formed a longitudinally extending slot through which the pin 26 passes.

When the marker is in use, the bar 28v is in the position shown in Fig. 1 with the outer end of the marker bar engaging the ground. If it is desired to raise the marker bar, the latch lever 31 is moved toward the seat 15 and this will cause the rack plate 21 to be moved downwardly in the housing.

As the plate 21 moves downwardly, the

and this will cause the arm 17 to be swung downwardly. As the arms swing downwardly, the pivot end of the bar is raised,

and this will start the free end of the marker bar downwardly. The marker bar by being supported during its upward and clownward movement is prevented from striking the ground with a violent blow and is thus prevented from being broken. After the lever has been moved to swing the marker bar upwardly, the operator can move the marker bar out of engagement with the hook 29 carried by the arm 17 at the right of the machine shown in Fig. 1 and into engagement with the hook 29 of the arm 17 at the left of Fig. l; The bar can then be lowered and will engage the ground upon the opposite side ofthe machine from that shown in the figure. It will thus be seen that the marker bar may be positioned to extend upon either side of the machine desired.

By having the device constructed as shown in Fig. 2, the marking attachment may be readily connected with the planters now in use and may be readily transferred from one machine to another.

It is, of course, obvious that if necessary, brackets 12 can be bent at any angle desired in order to properly connect the marker with the frame of the planter.

This marker is very simple in construction and is therefore not liable to readily get out of order or to very quickly break.

It should also be noted that by having the operating mechanism constructed as clearly shown in Fig. 1, the supporting arms 17 may be held at any desired angle, and that therefore the marking mechanism will op-. erate as efiiciently upon hilly ground as it will upon level ground.

If it is desired to raise the bar 28 so that it will immediately pass to the opposite side of the machine, the lever 31 may be moved a sufficient distance to bring the end of the marker bar out of engagement with the ground, and after the machine has been turned and started in the proper direction, the lever 31 can then be moved rapidly toward the seat 15 and thus cause the bar 28 to be swung upwardly and past the vertical position into engagement with the forked end 29 of the opposite supporting arms 17. The lever 31 can then be moved back to its original position and cause the supporting arms to be lowered. As these arms are lowered, the bar 28 will fall of its own weight and rest in the lowered position upon the opposite side of the machine from that shown in Fig. 1.
